AI Thread Summary
Young's interferometer is primarily known for demonstrating the wave-particle duality of light and interference patterns. Beyond these applications, it serves as a diagnostic tool for measuring the spatial coherence of wavefronts. Additionally, it can be utilized in astrophysics to measure the sizes of stars. The versatility of Young's interferometer extends its relevance in various scientific fields. Overall, its applications go beyond basic interference studies.

Other than using it to prove the particle and wave naturo of particles and of course show interference?

Or does it has some other use?
 
Physics news on Phys.org
A Young-type interferometer measures the spatial coherence of a wavefront. As such, it can be used not only as a diagnostic instrument, but also, IIRC, to measure the size of stars.
 
Thanks for the answers
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

Thread 'Raman Spectroscopy help'

I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
